President Donald Trump says he'll work to "get rid of and totally destroy" a provision that bars churches and other tax-exempt organizations from supporting candidates for political office.

Trump — in an appearance at the National Prayer Breakfast in Washington — says religious freedom is a "sacred right." He's not saying how or when he'd try to repeal what's known as the Johnson Amendment — after then-Sen. Lyndon B. Johnson, who pushed for it to be enacted.

Trump thanked Americans for their prayers as he begins his administration, saying they've been a "constant source of strength."

The president also took a dig at Arnold Schwarzenegger. He's the new host of "The Apprentice," the show Trump previously hosted. Trump says that since Schwarzenegger took over, the show's rating have been down, and Trump asked the audience to "pray for Arnold."

President Donald Trump is questioning whether the University of California at Berkeley should be granted federal funding. Trump urges the school to honor free speech.

Protesters hurled smoke bombs, broke windows and started a bonfire prompting university officials to cancel a talk Wednesday by Breitbart News editor Milo Yiannopoulos out of safety concerns.

Trump tweeted Thursday, "If U.C. Berkeley does not allow free speech and practices violence on innocent people with a different point of view - NO FEDERAL FUNDS?"

Berkeley cancelled Yiannopoulos' appearance after a crowd of some 1,500 gathered outside the venue.

The 32-year-old right-wing provocateur is a vocal Trump supporter and a self-proclaimed internet troll whose comments have been criticized as racist, misogynist, anti-Muslim and white supremacist.
